'NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 270,119, dated January 2, 1883.

` Application filed September 27, 1881. (No model.)

To all whom it may concern Be it known that I, EDWARD P. PRICE, a citizen of the United States of America, residing at Canton, in the county of Stark and State of VOhio, have invented certain new and useful Improvements in Nut-Locks; and I do hereby declare the following to be a full, clear, and exact description ot' theinvention, such as will enable others skilled in the art to which it Io appertains to make and use the same, reference being had to the accompanying drawings,\and to letters or figures of reference marked thereon, which form a part of this specification.

Y vFigure l isa section of a bolt, a nut, and a lock embodying my improvement. Fig.2 is an end view. Fig. 3 shows a device for holding the spring out'of engagement with the nut. In the drawings, A represents a bolt which, in the form shown, is adapted for use `in fast- V zo ening the plates to railroad-rails, though my improved lookin g device can be employed for other uses than thatjust mentioned.

a represents a groove formed in the side of the bolt, and extending from a point somewhat nearer the head ofthe bolt than the inner end of the screw-thread. It gradually increases in depth from the inner end to the outer, fora purpose that will hereinafter appear, and at the inner end it terminates in an aperture,f, which 3o passes transversely through the bolt.

B represents a nut adaptedto engage with the thread upon the bolt A, and provided with two or more grooves or slots, b, lying substan- -tially parallel to the axis of the nut.

Gis the loekingspring. It is formed of a piece of stron gsteel as small as possible without reducing its strength too much. At the inner end it is formed with an arm, c, substan tially at right angles to the shank g, said arm 4o being seated, when the lock is in position, in

the aperturej' of the bolt A. The shank g is somewhat thinner at the inner end, as at h, than at the outer portion, in order that the said thinner part may operate as a spring to throw 4 5 the outer part away from the center ofthe bolt. When the outer end ot' the spring is depressed it can be forced entirely below the threads of the bolt, and when in this position the nut can he turned freely to and fro upon the bolt. 5o After the nut has been adjusted in the desired 4the grooves b in the nut B.

having an aperture extending entirely through the bolt, and I do not claim such construction,

position the spring is released, andr it is immediately thrown outward to engage with one of rlhe outer end of the spring extends beyond the end of the bolt, and is formed with a notch, e. By `means of S5. this notched projecting portion the spring can Abe readilyforced inward out of engagement with it. By means of'a ring, or of a device similar to that shown at E, Fig. 3, adapted to fit the operators foot, and adapted also to engage with the notch e, the operator can release the spring in such manner as to have both hands free for the purpose of turning up the nut, and in this way the nuts along a railroadtrack can be very rapidly tightened, and it can 6 5 be done with greater power than when use is made of the springfastenings heretofore employed. l

I am aware that nut locks have been made in which the bolt has a longitudinal slot adapted to receive a longitudinal spring engaging with the inner surface of the next, and that suoli springs have been made with projecting ends, bywhich they may be pressed inward that the next may be turned; and I do not claim such devices as myinvention,which consists in the Inode of securing thc spring in the bolt, and in the combination, with such a spring adapted to receive it, of a-device for more conveniently operating the spring.

When a detachable spring of this character is secured by letting an arm of it perpendicularly into the bolt it is essential that the aperture for this arm should pass entirely through the bolt to afford means for pushing the spring out if its arm should become jammed or rusted in the aperture, in which it is designed toA lit snugly. It will readily be seen that a pull upon the free end ofthe spring would have no effect to release the arm c, and without the means I have provided there is great inconvenience in separating the detachable spring from the bolt.` l

I am aware that bolts have been constructed broadly; butIam notaware that they have ever been used for the purpose for which I have employed them-viz., to-,form the seat for a detachable and non-malleable spring, as shown, ion

enablingmeto detach said spring withoutbendthe spring may be releasedffrom the nut, sub- :o ing it by the application of a direct thrust to stantially asset forth. the seated end. In testimony whereof I affix my signature in What I claim s d presence of two witnesses. The combination,.with the slotted bolt an longitudina spring secured therein, projecting EDWARD P' PRICE' therefrom and having the notch e in its end, Witnesses: of the foot-stirrup E, adapted to engage with HENRY FISHER, the notch e in the end of said spring, whereby J.
